By providing a horizontal transfer section for transferring and a descending transfer section for transferring the plate to be baked, the plate to be baked can be heated in both the ascending transfer section and the descending transfer section. As a result, the length dimension along the transfer direction of the plate to be fired in the high-temperature heating chamber, that is, the horizontal length dimension, the height dimension in the ascending conveyance section and the height dimension in the descending conveyance section Since the total length can be shortened by the total amount, the overall length of the entire device in the horizontal direction is further shortened, and the above-mentioned effect can be promoted.

An elevating / conveying section for transferring the plate to be fired so as to move up and down is provided in a portion inside the heating chamber, and further, a portion in the cooling chamber of the transfer path is provided with the plate to be preheated in a substantially horizontal posture. Since the preheating chamber and the cooling chamber can be arranged vertically by configuring the horizontal transport section in the heating chamber in the reverse direction in which the horizontal transport section is transported in the opposite direction, the firing furnace device is installed. The floor area can be further reduced by the first and second inventions.
